My local routes were the #53 & #54 which went out to Stechford along Bordesley Green (I think one went via Deritend and the other via Fazeley Street), and the Coventry Road Routes #57 out to the Rover Works at Lode Lane, #58 to Sheldon and #60 to Cranes Park Estate.
Going-to-work buses were the #28 (City to Great Barr via Small Heath, Ward End, Castle Bromwich, Erdington & Short Heath), and the Tyburn Road Routes #66 to Pype Hayes and #67 to Castle Vale.
